If watching this page/thread, do you get notifications where applicable? (by e-mail)
It is the If one wants to watch only specific threads on a discussion page (not all of them), then don't watch the page itself. part that I don't believe works correctly with the current version LiquidThreads. I have never gotten it to notify me on an individual thread.
(I think the current LQT actually "watches" a particular posting, and not its replies... so it is not useful for watching a thread.)
